Christian Gentner then struck the right post on the half-hour mark for Wolfsburg, but Grafite doubled the advantage three minutes later, collecting Dzeko's pass from the left side and holding off pressure from Mario Eggimann before beating Enke.

Grafite made it 3-0 three minutes later, again making the most of some poor defending to fire home from the left side of the area.

Wolfsburg added their fourth nine minutes after the break when Zvjezdan Misimovic curled a cross into the box and Dzeko headed home from six yards.

Hannover almost pulled one back when Jiri Stajner hit the crossbar in the 66th minute.

But Dzeko completed his hat-trick with 10 minutes left, heading home Yoshito Okubo's cross to round off a successful afternoon for the visitors.
